Lets's calculate LCM of 617,790
Given numbers has no common factors except 1. So, there LCM is their product i.e 487430
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/487430
Therefore, the GCF of Fractions 866/617,930/790 is 2/487430
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 617,790 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(617,790) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(617,790) x common factors =1 x 1 = 1
LCM(617,790) = ( 617 × 790 ) / 1
LCM(617,790) = 487430 / 1
LCM(617,790) = 487430
